Key result
Patient-specific simulation reveals disturbed flow patterns in stenosed versus normal carotid bifurcations.
Why the study?
Numerical simulation can help demonstrate disease progression and hemodynamics in cardiovascular diseases such as atherosclerosis, but patient-specific hemodynamic analysis at carotid bifurcations is needed.
Comparison
Stenosed right carotid bifurcation vs normal left carotid bifurcation
Design
Patient-specific numerical simulation using two-way sequentially coupled transient FSI analysis

FSI simulation reveals disturbed flow and elevated hemodynamics in stenosed ICA versus normal; leaves open whether patterns predict progression or inform intervention.
Patient-specific fluid-structure interaction simulations can effectively demonstrate disturbed hemodynamics in stenosed carotid arteries, highlighting their potential utility in predicting disease progression and plaque rupture.
Khader et al. (2015) studied Carotid artery stenosis (n=1). Fluid-Structure Interaction (FSI) numerical simulation vs. Normal left carotid bifurcation was evaluated on Hemodynamic parameters including flow pattern, Wall Shear Stress, pressure contours and arterial wall deformation. Numerical simulation of a patient-specific carotid bifurcation revealed disturbed flow patterns and increased flow behavior in the stenosed carotid compared to the normal carotid bifurcation.
